This report details an extremely rare case of patent ductus venosus in a 29-year-old male. The condition presented as a large liver shunt, leading to gastric bleeding and anemia.

Area of Science:

  • Hepatology
  • Vascular Surgery
  • Gastroenterology

Background:

  • Patent ductus venosus is an exceptionally rare congenital anomaly, with limited documented cases globally.
  • This study presents a unique case of patent ductus venosus in a 29-year-old male.

Observation:

  • The patient presented with melaena stool and severe anemia, attributed to gastric hemorrhagic ulcers.
  • Initial investigations revealed normal liver function and ammonia levels, with negative viral hepatitis markers.
  • Imaging identified a significant 12 mm shunt in the liver, connecting the portal vein to the left hepatic vein.

Findings:

  • Percutaneous transhepatic portography confirmed a large shunt between the umbilical portal vein and the left hepatic vein.
  • Liver biopsy revealed an absence of portal venules in the portal areas, with no signs of fibrosis or inflammation.

Related Experiment Videos

  • The shunt's specific anatomical location led to the diagnosis of patent ductus venosus.

    • Implications:

    • This case expands the understanding of patent ductus venosus presentations and diagnostic findings.
    • Highlights the importance of advanced imaging in diagnosing rare vascular anomalies.
    • Contributes to the scarce literature on patent ductus venosus, aiding future research and clinical recognition.
